Be careful. Quite a few mitsu motors have interference valves. Check that you are lined up and then crank over the motor with a breaker bar. If you are off, the valves will hit the pistons. IIRC, the upper intake has a reusable metal gasket.(At least the older ones do.) Don't even have to take off the vaccuum lines. Also, mitsu's hydraulic tensioners are garbage and don't like to be pressed back in. I would recommend replacing the tensioner, seals, and waterpump while doing the belt. I quit being a mitsu tech in 99, so i could be off on the above.
